Answer 1

Answer:

$\large\boxed{A).\,10\%}$

Step-by-step explanation:

In this question, we're trying to find the probability of a male that also studies Spanish.

In this case, we know that:

• There's a 40% chance of a student being a male
• Probability of a male that studies Spanish is 25%

With the information above, we can find the probability.

To find the probability, we would need to find how much of 40 is 25%.

To do this, we would multiply 0.4 (40%) by 0.25 (25%) to find our probability.

Solve:

$0.4 *0.25=0.1\\\\\text{Move the decimal places two times to the right}\\\text{to turn it into a percent}\\\\\boxed{10\%}$

The probability of a male that studies Spanish is 10%

Your answer would be A). 10%

I hope this helped you out.

Good luck on your academics.

Have a fantastic day!
